Triceratops horridus or prorus

[GTS]

Triceratops horridus (or prorsus) (Marsh, 1889 /1890)

Late Cretaceous, c. 67 Ma

Hell Creek Formation,

Powder River Co., Montana

After acquiring a gorgeous T. rex tooth, I could not resist the opportunity of acquiring a tooth of its likely prey - Triceratops.

I’m aware of the difficulty in identifying ceratopsian teeth and the impossibility of distinguishing between T. horridus and T. prorus. As Triceratops  is the most commonly encountered genus within the HCF, this is labelled as being Triceratops horridus or prorus in my collection. I understand that the locality is known for T. prorus so it may well be that this is T. prorus.

 

I love this specimen for it still having the root - so unlikely to be a shed tooth.
